Comparative Security Matrix

Below we tried to quantify relative level of security based on the criteria discussed above. Of course this methods has its limitations (we assume equal weight of each component of the metric and the scoring is subjective). Still I think that total scores provide some useful insights into the integral security of the OSes involved. Here are total scores for each OS. The total cores are as following:

Red Hat Suse Solaris on Sparc Solaris on Opteron AIX HP-UX Windows
148 137 176 163 159 150 129 (+12)

Notes:

Below we will reproduce the whole matrix:

Name Red Hat  ES SuSE Solaris on Ultra
Sparc
Sola-ris on  Opte-ron AIX HP-UX on  PA RISK Win-dows Server 2003 Notes
Accounts and passwords  security 8 8 8 8 8 7 8 Linux provides reasonable level of account security but it does not support RBAC. Some features of RBAC can be emulated via sudo that is preinstalled in both Red Hat and Suse distributions.
Root security 7 7 6 6 6 6 n/a In Linux root by default has in own directory /root that improves the security of this account.
Filesystem security

Linux provides an extensive set of filesystems mounting attributes and can mount filesystem as read-only and NOSUID. Still virtualization capabilities are very rudimentary and here Linux is far behind leading commercial Unixes (AIX and Solaris).  Linux has only basic filesystem virtualization mechanisms (chroot)
File Permissions 8 7 9 9 9 8 8 Some Linux filesystems like Ext3 support ACLs but quality of support of ACLs in commercial Unixes is higher.   Ext3 supports BSD-style extended attributes.
Integrity checking 8 7 8 8 6 6 7 Linux approximately equal Solaris in integrity checking capabilities and Red Hat ships with Tripwire as an installation option. Still in Linux there is no MD5 database like in Solaris although some features of it can be emulated using RPM database.
Shell and scripting security 7 7 8 8 8 8 8 Neither operating system have advantages in this area but Linux has some additional vulnerabilities due to a large number of shells and scripting languages installed by default.
SSH support 8 8 8 8 6 6 5 Like in Solaris in Linux ssh is supported out of the box (is an installation option)
PAM support 9 9 8 8 6 6 5 Linux looks quite competitive with Solaris and has wider selection of PAMs then Solaris. Both of them definitely surpass AIX and HP-UX.
X11 security 4 4 6 6 6 6 n/a The problems with X security on Linux are mainly due to lesser security of  its desktop managers Gnome and KDE (especially Gnome).
TCP wrapper support 8 8 8 8 6 6 1 Linux has TCP wrapper functionality ion xnetd daemon
NFS 6 6 9 9 8 8 5 Linux NFS support is rudimentary and is not that stable.  Solaris has a much better implementation.
Built-in firewall 8 8 8 8 6 6 8 Linux has a built-in firewall that is enabled by default
Quotas enforcement and accounting data collection 6 6 8 8 8 8 8 Commercial Unixes are still superior in this area.
Logging 6 6 8 8 7 7 7 All Unixes are approximately equal in this area, but Linux has better log postprocessing tools. Solaris has much better kernel based logging mechanisms that help in the debugging.
Patching process quality

8 8 Patching in Linux involves updating the whole packages. Patching process in both Red Hat and Suse is weaker then Solaris patching process and patching support requires maintenance contract.
The number of Exploits and Hacking Attacks Statistics

4

4 8 7 8 8 4 As for number exploits Linux is less secure then commercial Unixes; it can be rated as equal in insecurity to Windows.
Process security

6

6 9 9 10 6 8 Solaris 10 has zones, AIX 5.3 partitions available by default.
Kernel security 4 4 9 8 9 7 6 Security of the kernel in Linux is hampered by the number of contributors and complexity of the built process.  Security-wise Linux kernel does not have capabilities of Solaris or AIX kernels.
Network security

4

4 8 8 7 7 4 Linux network security is bad due to the number of installed network applications.
Package management 8 7 6 6 4 4 6 RPM is an impressive package manager created by Red Hat and Red Hat RPM based packages dominate among all applications in Linux space.

Education and Security Certifications

9 7 8 7 7 6 10 The number of books devote to Red Hat security is considerable and by an order of magnitude surpass the number of Solaris books. Red Hat offers four security-related training courses (approximately the same as Sun for Solaris). We judge that in this area Linux surpasses all other Unixes and trails only Windows.

Hardware Related Security Issues

6 6 8 7 8 8 6 32 bit Intel hardware is the most hacked hardware in existence and is widely available to hackers of any country on the globe. By just switching to 64-bit hardware we can somewhat decrease hardware-related security risks.
